Imagine you are standing in front of a full-length mirror. Naked. You have been asked to gaze at yourself for two minutes.
Now take a quick inventory of the feelings that were aroused by this suggestion. Did you feel curious or afraid? A fuck yes, I am hot or a bitchy voice tearing your body apart? Interested or hesitant? Willing or unwilling? Or did you reject the whole idea as something you would absolutely never do? Imagining the experience gives you an indication of your level of self-acceptance; actually doing it will tell you even more.
